Williams Thomas has refused to name publicly the offenders because he fears identifying them may force them underground – but has taken his concerns to British police and the Home Affairs Select Commitee.

Sadly, many other countries have far weaker child protection laws, making access to offend much easier.

“I am aware of British offenders currently in areas where child abuse is prevalent.

“Convicted child sex offenders should not be allowed to travel abroad to countries where child sexual exploitation is high. We should be ensuring convicted child sex offenders have passports taken away from them to limit travel.

“Child abuse is prevalent in Burma, Cambodia, Thailand and the Philippines, to name just a few.”

Williams Thomas was alerted to the paedophiles’ breaks by concerned campaigners who contacted him on social networking site Twitter, and began to investigate further.

He has written to head of the Home Affairs select committee and the director of the National Crime Agency to alert them to the alarming situation.

The true nature of Jimmy Savile’s character was exposed as a result of Williams Thomas’ ITV documentary Exposure: The Other Side of Jimmy Savile.

Following the programme, police launched Operation Yewtree which has investigated the hundreds of allegations of child abuse by the formerly revered DJ and fundraiser.

Celebrity publicist Max Clifford, children’s entertainer Rolf Harris and radio and TV presenter Stuart Hall have all been jailed as a result of the police probes that followed the programme.
